1. The problem statement, all variables and given/known data A car traveling in a straight line has a velocity of 5.51 m/s at some instant. After 7.36 s, its velocity is 8.09 m/s. What is its average acceleration in this time interval? Answer in units of m/s^2. 2. Relevant equations avg. acceleration = (v2 - v1) / (t2 - t1) 3. The attempt at a solution (8.09 m/s) - (5.51 m/s) / (7.36 s - 0 s) = .350 m/s^2 --------------- The only thing I'm not sure about is the "0s" used above: is that the right interval? I'm confused if I'm approaching this right, so could anyone help me please? Thanks!
